If I have 3.9 L of gas at a pressure of 5.0 atm and a temperature of 50.0 0C, what will be the temperature of the gas if I decrease the volume of the gas to 2.4 L and decrease the pressure to 303.0 kPa?

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1

The mass of a neutron is equal to the mass of a proton plus the mass of an electron. true or false false true
